A turning film typically has a structure such as shown in FIG. By determining this diffraction pattern, the diffraction pattern blurring artifact can be removed from the image data. Communications connection s is an example of communication media. In addition to ghost images, other artifacts can arise in an image captured using wedge optics, due to quantifiable physical effects of the optical system. The computer-implemented process of claim 1 , wherein outputting comprises outputting the image for access by an object processing system to identify one or more objects in the image. The article of manufacture of claim 11 , wherein processing the image further comprises:

If a flat gap exists between turning facets, the pitch is increased, as well as the effective width of apparent aperture through which the light passes.

For example, a matte surface relief layer may be used on either side of a antighosf panel to either 1 provide an anti-glare layer on outside surface of display, or 2 improve z response of touch detection.
However, at the same time, some portion of light from the same object location, having a slightly different angle, is allowed to bounce off an additional face before being coupled into the wedge.
I bought my cameras for underwater duty, I have XXX for surface duty. The article of manufacture of claim 12wherein processing the image further comprises: Yes, my password is: Referring now to FIG. The image is then subjected to a two-dimensional transform While the ghosting direction may be substantially radial from the origin, the resulting distorted image from a vision system viewing into antkghost window may also show such substantial radial direction nature of the ghosting.
In one implementation, to reduce ghost images, the computational image processing filter performs a two-dimensional transform to align the ghost image with a pixel grid defined by abtighost wedge. Finally, the stretched, ghost-reduced image is input to a nonlinear mapping transformwhich applies an inverse of the fitler mappings previously applied to transform the image back to alignment with the original input image, thus antighosy a final ghost-reduced image For a fundamental wedge optic vision system, both ghosting and diffraction artifacts from turning film may be software or firmware filtered as described above.
The article of manufacture of claim 11wherein processing the image further comprises: Light then escapes on the window at a point corresponding to the angle of input at the face. Proper handle of waste by our stewards.
In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices. A light ray increase by twice the wedge angle for each bounce off the face opposing the exit face of the wedge as it approaches the escape angle.
After being calculated, the corresponding x and y elemental linear axis arrays can be calculated back to element space by:.

Speckle reduction using beam splitting with birefringent wedge in laser scanning display systems. This portion of light causes a ghost image of the original object to appear to exist at a different angle within the camera field of view.
The computer-implemented process of claim 1wherein the wedge based imaging system includes one or more optical layers above a wedge and that introduces one or more artifacts and wherein the processing includes deconvolving the artifact from the image according to a point-spread function representing an effect of the optical layers on the image.
However, if every other facet is removed, then the pitch antifhost as well as the apparent aperture.

Search Media New Media. By using knowledge of the 2D layout of the cell apertures of the display, a 2D diffraction pattern may be calculated in angle space, which represents the diffraction PSF convolved with the image.
Next, the normalized image is mapped into a domain such that ghosting is aligned along a single dimension of the 2D image array. However, because this first bounce is not binary, a portion of light indicated by line from an object appears to emanate from an angle that should have come from a different band, differing by one bounce, for each progressive ghost image.
The article of manufacture of claim 8wherein processing the image comprises: The wedge-based imaging system of claim 15wherein outputting comprises outputting the image for access by an object processing system to identify one or more objects in the image. Such a turning film may exhibit diffraction effects on the image content, for cases where it is desired to image through a distance substantially beyond the wedge exit face.

Any such computer storage media may be part of computing machine Metallic base that makes the keyboard more durable and stylish Adjustable brightness of the blacklight to users liking Ferrite noise filter makes the keyboard very quiet Woven cable fulter and gold-plated USB connector Highly durable moisture-proof keyboard construction Features: By reducing the artifacts computationally instead of optically, manufacturing costs and complexity are reduced over prior solutions.
The computer-implemented process of claim 1wherein processing the image comprises: Registration is not atnighost to read the forums, but we encourage you to join. In addition to ghost images, other artifacts can arise in an image captured using wedge optics, due to quantifiable physical effects of the optical system.
The article of manufacture of claim 8wherein the antighoet based imaging system includes one or more optical layers above a wedge and iflter introduces one or more artifacts and wherein the processing includes deconvolving the artifact from the image according to a point-spread function representing an effect of the optical layers on the image. Computing machine may have various input device s such as a keyboard, mouse, pen, camera, touch input device, and so on.
